Prothane 7-1057-BL Leaf Spring Eye Shackle Bushing Kit - Black

The Prothane 7-1057-BL is a complete leaf spring eye and shackle bushing kit crafted from premium HYPER-Flex polyurethane, engineered as a direct upgrade over worn or deteriorated OEM rubber bushings. In leaf spring suspensions, pivot points and shackles endure some of the highest stress loads in the entire suspension system — making bushing quality critical to handling, safety, and longevity.

Prothane's polyurethane compound is specifically formulated to provide significantly greater durability and dimensional stability than factory rubber, resisting the compression set and degradation that causes OEM bushings to blow out over time. Each bushing in this kit is precision-formed to exact application specifications, ensuring a direct-fit installation with no trimming or modification required.

Key Features:

• Made from Prothane's HYPER-Flex premium-grade polyurethane for superior strength and longevity
• Replaces soft, failed OEM rubber leaf spring eye and shackle bushings
• Precision-fabricated components including all related sleeves for a perfect fit
• Black finish for a clean, professional appearance
• Resists oil, grease, and environmental degradation better than rubber
• Provides improved suspension rigidity while retaining enough compliance for street use
• Made in the USA

This kit includes all necessary bushings and hardware components needed for a complete replacement at both the spring eye and shackle locations. Professional installation is recommended to ensure proper fitment and alignment.
